「Attitude of Authenticity」Vol.1: Indigo Dying by Mr.Yoshizawa

Date : 2020/01/31Category : NewsMedia

(Japanese below)
One of Pizza 4P’s brand values is “Authenticity”. It’s kind of a policy that we always ask, deeply think about “what is being authentic?” to create pieces of work and bring about real creation, not that one takes things superficially or imitate them. We’ve collaborated with and shared thoughts with creators who we think have such an attitude. 

From now on, we’d like to share spirits and thoughts of authentic creators who have been involved in Pizza4P’s through the serial articles named “Attitude of Authenticity”. 


As the first article of” Attitude of Authenticity”, I’ll introduce Takeshi Yoshizawa (Japanese) who lives in Hanoi and engages in activities as an indigo dying master and her wife, Thanh (Vietnamese). They joined an indigo dying project at Pizza 4P’s INDOCHINA DA NANG which opened last December. The customers applauded the design full of craftsmanship with indigo curtains which spread over the whole big windows and indigo-made walls applied repeatedly and elaborately over time. Actually the color of indigo is the corporate color of Pizza4P’s and an very precious for us as well. This time, I’d like to deliver a story about such “indigo dying” to you.

Pizza 4P’s:I have never seen such gigantic walls dyed in deep indigo. 

Yoshizawa:I was very surprised and happy to hear that Pizza4P’s wanted to paint the big walls of over 100m2 in natural indigo. The concept of the new restaurant is “fermentation of the place” which comes from the fermentation of Pizza dough. I heard that the restaurant focuses on natural and recycled materials in order to express the concept. I was honored that the great value of natural indigo was discovered. 

However, I was worried because, this time, I wouldn’t use indigo for a cloth as a dye, but paint it on an inorganic wall, which I had never experienced before. It was a big challenge for me, because I was not able to grasp the whole picture even after lots of research. It might not go well. Only I could do was just try it anyway. 

Pizza 4P’s: It was a difficult situation with no preceding examples, wasn’t it? 

Yoshizawa: Dyes such as indigo and pigments such as paints and colors are different in the first place. In case of dyes, coloring matters are combined molecularly with fibers such as a cloth and a string to create the state of “being dyed”. In case of pigments, on the other hand, a color puts on a surface and lets it dry to create the state of “covering the color underneath”. 

At the first trial, I simply applied dying liquor on the concrete wall, but the color didn’t stay nor develop. It’s only natural because it cannot permeate inside. Then, I mixed it with plaster which was often used as an ingredient to paint a wall. However, indigo didn’t develop its color even after it is mixed in the plaster because indigo develops its color by getting oxidized while indigo exposes to air. Then, I came up with an idea of mixing the liquid made in the course of creating dying liquor with the plaster and mixing it also with dying liquor to apply on walls. After that, I repeatedly experimented in several ways. But it was less than 4 weeks until I would open the restaurant when I reached an idea which seemed feasible and I got really frustrated with it.

Pizza 4P’s: Things actually went well? 

Yoshizawa: Well, actually not because the color didn’t stay. However, I tried to come up with a new idea, ordering muddy Indigo from Hanoi to increase concentration of dye and decided to repeatedly apply twice as much dye as when I experimented after all. It was time and labor-consuming work. I was not able to apply it at once. I added muddy indigo into dying liquor and let it take rest for a few hours and went ahead while keeping the state of indigo. 

Luckily, I’d been blessed with weather and had enough sunlight and temperature, which made indigo perfect. I’d worked until the morning of the opening day applying indigo for 7 times and cleansing/settling it for 3 times after all. 


Pizza4P’s: You’d done it until the very last minute. How about the indigo curtain?

Yoshizawa: I think Indigo is a very assertive color. It defines the whole space and atmosphere especially when it is used for interior. Strong indigo makes the room dark and light one makes management of uneven dying difficult. Indigo is vulnerable to sunlight and gets sunburn as well. I needed to create design appropriate to a minimum and modern restaurant. 

At first, I was told that gradation would be good, but I proposed a curtain with the color of indigo and the unbleached arranged alternately and various tie-dye patterns applied in some parts when a curtain is drawn. As for tie-dye, I used different patterns for 14 curtains. Some of them are traditional ones from ethnic minorities in Vietnam. As for nuitorishibori (a pattern-making method) comes from a hood worn by an ethnic minority of Sapa. The small starry pattern is a tie-dye pattern of a hood worn by an ethnic minority of Lolo. 

Pizza 4P’s: You introduces traditional approaches of Vietnamese ethnic minorities. That’s impressive. 

Yoshizawa: I had engaged in textile jobs for a long time and visited textile-dyeing sites in Asian countries. Each traditional textile has an excellent handicraft technique that has been handed down for many centuries and is a precious cultural asset. However, I witnessed such valuable things disappearing while the economy was developing at a rapid speed after the 1990s. I felt a sense of crisis about this and started a project with original organic products that were made by Sapa, an ethnic minority living in the Northern mountain area in Vietnam. Since my wife was born and raised in Sapa, I thought I would truly understand and respect their culture.  

Pizza4P’s:Why did you get interested in tradition of such ethnic minorities? 

Yoshizawa:When I first visited Sapa, I was quite surprised by the fact that all men and women, young and old wore ethnic costumes appropriately while protecting their ancient animism and the traditional belief. Here, textile-dying culture and the sense of value, the sense of world and the religious world that support such culture were seen everywhere just like it’s only natural… or like air. 

Ethnic minorities living in Sapa such as Black Mon, Red Dao, Zai, Black Tai and Safo have their own distinctive cultures, the religious worlds and costumes. I was impressed that they were proud of those and lived a humble self-sufficient life with great smiles in nature although they were all poor. I thought I would tell these to all of you or to the future.

Pizza4P’s:It seems very difficult, but is it actually possible to hand down such cultural values? 

Yoshizawa:Although there are only a few villages by now, but in some villages where we started activities at an early period, handicraft techniques have been handed down from aged and skilled workers to the next generation. Right now, the young generation is discovering meanings to the succession as one of economic activities. Therefore, it is necessary for them to understand how the works they are making deserve to be proud of and how valuable they are. Respecting, motivating, appreciating them and listening to unreasonable things that they’ve suffered are our great tasks.

Pizza4P’s:I was impressed with such a big ambition. I’m really honored to join the activity.

Yoshizawa: I believe that ancient textiles and dyes that have been continued over many centuries can’t be compared to mass production that can be easily achieved with the modern science technology in this 21st century. Craftsman’s lengthy period, efforts, pray and thoughts, various colors and smells are woven into their cloth and also long stories grown in the climate of the Northern Vietnam are dyed into it. 

Right now, the big transition has come to the mountain area in the Northern Vietnam. Sapa, which used to be a quiet village, is one big tourist destination with numerous high-grade hotels. Things that have occurred in other countries actually started in this country as well.  Nobody can stop this trend. The change of lifestyle makes wearing costumes by an ethnic minority fade away. If they wear costumes less and less, techniques to make costumes will go into decline. Now that there are only a few skilled craftsmen, it is no longer easy to take back what has gone. 

Pizza4P’s:Is there any hope all the same?

Yoshizawa: As interests in organic materials are increasing every year in the world, it is also likely to boom in Vietnam. Some young people in urban areas with a new sense of value started to review Vietnamese own culture. They wear traditional costumes and natural elements as one of fashion items and try to create a new demand in Vietnam. 

The time has come when we are able to always share a sense of value across a border or race on the Internet. If we connect the next-generation creators with a new sense of value and create opportunities to make a totally new values and demands, we have a slight hope for the future, which is our true role. 

Pizza4P’s:Well, that was a wonderful story. Thank you very much.


I ‘m really taking off my hat on energetic passions that Mr. Yoshizawa and Ms. Tain want to hand down Vietnamese tradition and cultural values to the future generation. All staff of Pizza4P’s are very honored to work together with you two and other members. Our roles are to tell their spirit even if a little through medium called a restaurant. 

You can see indigo-dying walls and curtains with full of their thoughts can be seen Pizza4P’s INDOCHINA DA NANG which opened in December, 2019. Please visit to experience this wonderful project. I’m sure you will feel warmth or an abundant heart and gain lots of inspiration.

PIZZA 4P’Sのブランドバリューの一つに“オーセンティック”というものがあります。それは物事を表層的に捉えたり模倣するのではなく、「オーセンティックであるということはどういうことか?」を常に問い、深く思考し、注意深い洞察を重ねながらプロジェクトを行っていくというスピリットです。そして私たちはそのために多くのオーセンティックなスピリットを持ったクリエイターたちとコラボレーションを行っています。

今後は「Attitude of Authentic」という連載記事を通して、PIZZA 4P’Sに関わっていただいている素敵な人々のスピリットや思想をシェアしていきたいと思います。

「Attitude of Authentic」の第一弾としてご紹介するのは、ハノイを拠点に活動する藍染職人の吉澤岳史さん(日本人)と、ベトナム人の妻タインさんです。お二人には、12月にオープンしたPIZZA 4P’S INDOCHINA DA NANGの藍染プロジェクトをご一緒させていただきました。大きな窓全面に配した藍染のカーテンや、時間をかけて丁寧に重ね塗りをした藍でできた壁など、そのクラフトマンシップ溢れる意匠に、さっそく多くのお客さん「素晴らしい!」という賞賛の声をいただいております。この藍色、実はPIZZA 4P’Sのコーポレートカラーでもあり、私たちにとってとても大切な色でもあります。今回はそんな「藍染め」の話をお届けします。


PIZZA 4P’S:このように深い藍色で染まった巨大な壁は、今までに見たことがありません。




PIZZA 4P’S:前例のない中で、かなり困難な状況だったんですね。



最初の実験で単純にコンクリート壁に染液を塗ってみましたが、色が定着することはなく発色もしませんでした。中に染み入ることができないので当然です。そこで壁に塗る素材としてよく使われる漆喰に混ぜてみました。ところが藍は空気中の酸素に触れることによって酸化して発色するため、漆喰の中に藍の材料を混ぜても、空気に触れないので発色しません。 そこで藍の染液を作る途中にできる液体を漆喰の中に混ぜ、これを壁に塗る染液にも混ぜるという手法を考えつきました。そこから回数ややり方を何度も実験し、実現可能だという状態までたどり着いた時は、お店のオープンまで4週間を切っており、とても焦りました。


PIZZA 4P’S:実際には順調にいったのですか?




PIZZA 4P’S:本当にギリギリの状況で出来上がった作品なんですね。藍染のカーテンについてはいかがですか?






PIZZA 4P’S:ベトナムの少数民族の伝統手法を取り入れているのがとても印象的です。

吉澤:私は長年テキスタイルの仕事で、アジア各国の染織の現場を巡ってきました。どの伝統的な織物も何世紀も続いてきた卓越した手工芸技術で、貴重な文化遺産です。それが1990年代以降、急速に経済が発展していく中で、どんどん失われていくのを目の当たりにしました。私はこのことに危機感を覚え、べトナム北部山岳地帯の村「サパ 」の少数民族たちが作るオーガニック素材を使ったオリジナルプロダクトを展開するプロジェクトをはじめました。私の妻は生まれも育ちもサパなので、彼女たちの文化を真に理解し、リスペクトしたいという想いもありました。


PIZZA 4P’S:少数民族たちの伝統に興味を持たれたのはどのような理由ですか。






PIZZA 4P’S:非常に難しいことだと思いますが、実際に文化的価値の継承は可能なのですか。




PIZZA 4P’S:大きな志に胸を打たれます。活動をご一緒させていただき、本当に光栄に思います。

吉澤:この21世紀に何世紀にも渡って続けられてきた古来の織りや染めは、現代の科学技術で簡単に作ることのできる大量生産のものとは、比べ物にならないほど価値があるものと考えます。 彼らの布には彼ら作り手達の月日と手間、祈りと想い、様々な色彩と匂いなどが織り含まれていて、北べトナムの風土の中で育まれた永い物語が染め重ねられています。

現在、ベトナム北部山岳地帯にも大きな変化が訪れました。かつてのどかな村だったサパも、高級ホテルの乱立する一大観光地となりました。 他の国で起きてきたことがこの国でも始まりました。もはやこの流れは止められません。生活様式の変化により少数民族たちが衣装を着る意義も薄まりました。衣装を着なくなれば衣装を作る技術も衰退します。熟練の作り手たちがほとんどいなくなってしまった現在、なくなったものを取り戻すのはもはや難しいと言えます。

PIZZA 4P’S:そんな中でも希望はあるのでしょうか。





PIZZA 4P’S:本当に素敵なお話を聞かせていただき、ありがとうございました。


吉澤さんとタインさんのベトナムの伝統や文化的価値を後世に伝えていきたいという熱い想いには本当に頭が下がります。そして今回、お二人やメンバーの皆さんとご一緒させていただくことができて、PIZZA 4P’S一同とても光栄ですし、彼らのスピリットを少しでもレストランというメディアを通して伝えていくことが、私たちの役割だと考えています。

このような想いの詰まった藍染の壁やカーテンは、2019年12月にオープンしたPIZZA 4P’S INDOCHINA DA NANGでご覧になれます。ぜひこの素敵なプロジェクトを体感しにいらしてください。きっとぬくもりや豊かな心を感じたり、たくさんのインスピレーションを得られると思います。
